Geoinformation Management
Question 1
GMN621S
1.1. Namibia has been experiencing rapid growth in informal settlements since
independence. Many reasons have been attributed to this trend. The Namibian
government has designed programmes and projects to reduce this trend. Using the
management principles that you have studied, answer the following questions.
a) Problem Tree Analysis: Identify four (4) main causesof informal settlement growth
(i.e. 1st level).
(4)
b) For each of the main causes, identify two sub-causes (2nd level).
(8)
c) Objectives: Formulate the overall project objective and at least two purpose
(specific) objectives to address the problem (short-term and medium-term
objectives). Ensurethe formulated objectives are 'SMART'.
(6)
d) Activities: Outline solutions/activities to achieve the formulated objectives. Provide
at least two (2) sub-activities per objective.
(9)
e) Identify two (2) stakeholders for each of the following sections: (1.
Beneficiaries/target group, 2. Implementers, 3. local financing agents, 4. decision (8)
makers).
1.2. Give five (5) main reasons why proper planning is needed in GIS.

Question 2
GMN621S
2.1. The GIS planning and implementation methodology can be subdivided into four (4)
main phases and nine (9) planning stages. Name and briefly explain the four (4) phases. (8)
2.2. Briefly explain the four (4) main types of spatial errors that are possible in GIS.
(4)
2.3. Define what you understand by spatial data infrastructure (SDI) and name two (2)
types.
(6)
2.4. Explain the five (5) main elements or components of a Master Input Data List.
(10)
[28)
Question 3
3.1. You are a consultant hired to collect data for a GISfor urban development monitoring.
As part of your task, you must determine the appropriate scale and corresponding
primary data sources. Assuming you must produce a map for a town planning firm.
What would be the scale of the map if a 20 m x 40 m erf is 10 mm x 20 mm on the map? (2)
3.2. Now that you have determined the scale of your map, what would be the perimeter in
cm of a school sports field area on the map, if the perimeter on the ground is 1200 m? (2)
3.3. Assume a person offers you a 6.3-hectare (Ha) plot to buy and then shows you the
location of the plot on a map with the same scale as in (3.1). The plot which he shows
you is a rectangular polygon and measures 25 cm x 50 cm on the map. By how much
bigger or smaller (in ha) is this plot on the ground?

3.4. Let us assume that one of the important regular outputs of your GIS will be thematic
maps of an area which measures exactly 35 km in North-South and 65 km in the East-
West direction. Let us also assume that you have a printer that can only print up to a
maximum format of DIN A2 (420 mm x 594 mm) and that a strip of 1 cm on all four
sides of the A2 sheet cannot be printed. What would be the maximum scale at which
you could print these maps, showing the entire 25 km x 55 km area on one DIN A2
sheet? Note: A correct final figure result will only be counted if it is accompanied by a
reproducible and correct calculation.

Question 4
You have been hired as a consultant to spearhead the implementation of a mobile GIS App
for the NSA. After conducting a needs assessment and a technology development seminar,
you produced seven activities and their duration (in weeks) as shown in the table below.

4.1. Calculate the expected time for each activity.
4.2. Calculate the variance for each activity.
4.3. Construct the PERTdiagram.
4.4. Identify and determine the duration of the critical path.
4.5. Calculate the probability of completing 48 weeks.
4.6. Calculate the expected time if the probability is 95%.
Below are the given formulae to help you answer Question 4.
